Misalignment of shaft using image processing software Visionbuilder was calculated. The further purpose of this project was to check whether the image processing technique can be used in bone transplant surgery. The model of the hip was used for the experimentation purpose. Image processing software Visionbuilder was used to match the profiles of the bone before implant and bone after implant.展开更多
背景:正电子发射计算机断层显像(PET)从分子水平反映细胞代谢和功能变化,MRI有更高的软组织对比度和空间分辨率,且无电磁辐射。近年来,随着多模式成像技术飞速发展,作为刚刚应用于临床的多模式分子成像技术,PET/MRI融合显像可提供分子...背景:正电子发射计算机断层显像(PET)从分子水平反映细胞代谢和功能变化,MRI有更高的软组织对比度和空间分辨率,且无电磁辐射。近年来,随着多模式成像技术飞速发展,作为刚刚应用于临床的多模式分子成像技术,PET/MRI融合显像可提供分子、形态与功能信息,有关研究已成为分子影像领域的关注焦点。目的:就目前PET/MRI研制存在的问题和进展情况做一综述,并展望其潜在的临床和科研价值。方法:由第一作者应用计算机检索CNKI数据库、Springerlink数据库、Pubmed数据库相关文献。检索时间范围:2000年1月至2012年6月。英文检索词:"PET/MRI"和"multimodality imaging or image fusion",中文检索词:"分子影像学"和"图像融合"。选择内容与PET/MRI多模式成像相关的文章,同一领域文献则选择近期发表或发表在权威杂志文章,共纳入53篇文献。结果与结论:已有的研究成果表明,PET/MRI较传统显像手段和其他成功的多模式成像技术,如PET/CT和SPECT/CT有更多、更新的应用优势,并已积累临床前和初步临床应用的经验,PET/MRI具有广阔的发展空间,有望将分子影像技术的发展带入一个新的时代,为临床诊断掀开新的篇章。展开更多
